Is this possible in Systemd? Maybe an option to allow units to trigger multiple times? My next approach would be create a set of two services with different names (perhaps using a template) to run alternatively, but that also seems a bit hacky. I essentially want the shell script to run every 15 mins, no ifs no buts. This is a a bit of a hack, since if anything I would want to ensure continuity and have the files on disk overlap a little. This also makes sense and I've solved it by only dumping 899 seconds instead. This appears to work relatively well, except due to timing issues I find that a subsequent triggering of the timer won't start the service as the last run is still running, as it has a second or so left.
Delay Off Timer Relay - 15 Minutes 12V-0-740-57. I guess that makes sense, although I still don't understand why we need to be so explicit about these things (or indeed the difference between simple and oneshot). Comprehensive range of fixed duration timer relaysAvailable in both 12v 24v variants12 volt units are. dump-rtsp.sh rtsp://address/$i $i.mp4 &Īs an aside I found that the & in dump-multi.sh was only effective if the Type was set to forking. I then call this for each stream: #!/bin/bash I start with a script to do the dumping for 15 mins (I do some date math and setup which I've omitted): #!/bin/bashįfmpeg -hide_banner -loglevel error -i $1 -vcodec copy -t 900 -y $2 Navigate using the buttons including a reset button, pause button. Give yourself 15 minutes to finally write that letter to an old friend, or isolate a short window of time for quiet reflection on an important topic.I want to set up scripts and systemd timers to allow 24x7 dumping of 8 RTSP streams to disk, in 15 minute chunks, each starting on the quarter hour.
